“Zinc Plating – The Corrosion-Prevention Workhorse”


Whether you are walking through a hardware store, looking under the bonnet of your car, or cutting the grass, you will find zinc plating at work protecting steel from corrosion in the products we use every day. Zinc plating has found wide acceptance as a surface finish throughout all consumer, industrial, and commercial products. Although it is very common in our daily lives, few of us have paused to contemplate this important engineering finish, much less understand how it works.


Zinc Plating is widely employed for providing sacrificial protection to steel. Being electronegative to iron, meaning that the zinc will corrode preferentially to the underlying metal, zinc plating gives excellent corrosion resistance to iron and steel components, particulary in industrial and urban environments.


Zinc Plating provides an attractive finish with relatively uniform thickness, which does not tend to fill up slots and screw holes or obliterate threads and other fine details of work. The coating can subsequently be passivated or dyed to further improve corrosion resistance or for part identification.


Zinc Plating also serves an an effective undercoate for powder coated and wet paints.


Zinc Plating is available in varying colours - Zinc Dichromate (yellow/gold), Black Zinc and Clear (Silver) - See below.
